Radio communication base station device and radio communication method to shorten a suspension time of an mbms service when a user equipment moves from a single frequency network area to a non-single frequency network area

Abstract

Disclosed are a radio communication base station device and a radio communication method which can reduce the interruption time of a service being received by UE while suppressing a resource consumption amount in an SFN area when the UE performs a handover from the SFN area to a non-SNF area. An MBMS reception request identification unit () judges an RRC message inputted from the UE (). If an MBMS reception request is contained, an MBMS reception request is transmitted to an MBMS reception request storage unit (). Moreover, when the RRC message from the UE () contains an adjacent cell reception quality measurement result, a handover decision unit () judges whether to perform a handover to the adjacent cell. The MBMS reception request storage unit () stores the MBMS reception request outputted from the MBMS reception request identification unit (). When the handover decision unit () which has decided the handover requests for transmission of an MBMS reception request, the MBMS reception request storage unit () transmits the MBMS reception request to an MME ().
